    Notes: [Auszug] We used allantoic fluid from hens' eggs inoculated with influenza A, A2 or B virus. The fluid was centrifuged at low speed to remove membrane debris and centrifuged for a further 3 h at 100,000g to sediment viruses; the sediment was washed by resuspending it in buffered saline (pH 7.0) and then ...

    Notes: Abstract This paper employs conversation analysis to examine the inter-connection between grammar and displays of contextual understanding, social identity, and social relationships as well as other activities clustering around turn-endings in Japanese talk-in-interaction, while undertaking a restricted comparison with the realisation of similar activities in English. A notable feature of turn-endings in Japanese is the particular salience of grammatical construction on the interactional activities they accomplish. Complete turns which are also syntactically complete are shown to be associated with the explicit display of contextual features, whereas syntactically incomplete turns are designed to circumvent or minimise such displays. The explicit or implicit display of one's social and contextual relationship to the interactional environment is therefore seen to be an integral part of the performance of social actions in Japanese. On the other hand, in English, it is more difficult to establish a clear association between grammar and the inclusion or avoidance of contextual displays.

    Effect of dietary phosphate on Na+-dependent phosphate cotransporters function and expression in the rat kidney (1998)

    Notes: Abstract Background Three types (typeI, II, andIII) of sodium-dependent phosphate cotransporters have recently been isolated and shown to be expressed in the mammalian kidney. Understanding of the functional roles and regulation of each transporter is still fragmented, however. Methods We analyzed the functional roles of each transporter by using antisense oligonucleotides in theXenopus oocytes expression system, and by localization in the proximal tubules of rat kidney using immunohistochemistry. Results Phosphate uptake in brush border membranes was increased by about 2 times in rats fed a low-phosphate, as compared with a high-phosphate, diet. Expression of typeI, II, andIII transporter mRNAs was observed in renal poly(A)+RNA, isolated from the rats fed a low-phosphate diet. Phosphate uptake increased about 2.5-fold inXenopus oocytes injected with the poly(A)+RNA, compared with those given RNA from rats fed a high-phosphate diet. Hybrid depletion of the typeII sodium-dependent phosphate transporter (NaPi-2), but not of the typeI (rNaPi-1) or typeIII transporters (PiT-1 and PiT-2), significantly decreased phosphate transport activity in oocytes injected with the poly(A)+RNA from each experimental group rat kidney. In rats fed the lowphosphate diet, NaPi-2 immunoreactivity increased markedly in the brush border membranes of renal proximal tubular cells, whereas rNaPi-1 protein was not changed. Conclusion This study suggests that the typeII transporter functions mainly as a sodium-dependent phosphate cotransporter, and is regulated by dietary phosphate in the rat kidney.

    The influence of nephrectomy, ureteral ligation, and of estradiol on plasma renin substrate in unilaterally nephrectomized rats (1976)

    Notes: Summary The effects of three experimental conditions on the concentration of plasma renin substrate were studied with special reference to plasma renin concentration in unilaterally nephrectomized rats. After simultaneous bilateral nephrectomy the maximum increase in plasma renin substrate was 17 times higher than normal within 24 h, while in rats which were unilaterally nephrectomized 10 days previously, followed by the removal of the remaining kidney (two-step bilateral nephrectomy), the maximum increase in plasma renin substrate was markedly suppressed (6-fold of normal). The maximum increases in plasma renin substrate by estradiol treatment in normal and unilaterally nephrectomized rats were about the same, associated with similarly decreased plasma renin concentrations. The similar increase in plasma renin substrate was found after ureteral ligation in unilaterally nephrectomized rats and bilateral ligation of the ureters in normal rats. This was the case where the plasma renin concentrations changed differently after ureteral ligation. After two-step bilateral nephrectomy plus estradiol treatment the maximum increase in plasma renin substrate was found to be higher than that found after two-step bilateral nephrectomy, but was lower than that after simultaneous bilateral nephrectomy. It is suggested that under the pathological conditions that stimulate renin substrate production, the plasma rein substrate concentration is less affected by circulating renin.

    Cloning and mapping of the sporulation gene, spoT7, in Saccharomyces cerevisiae (1985)

    Details

    Topics: Biology
    Notes: Summary In order to isolate a DNA fragment able to complement a sporulation-deficient mutation in Saccharomyces cerevisiae, a simple screening procedure was devised which was based on the difference in osmotic sensitivity between protoplasts and spores. A plasmid (pHT7) containing a 13 kb DNA insert that complemented the spoT7 mutation was isolated from a yeast genomic library prepared in the vector YEp13. Gene spoT7 was linked to rna1 at 1.2 cM and to mak27 at 7.2 cM on the right arm of chromosome XIII. Mapping of the cloned gene following integration into the chromosome showed that the cloned gene was allelic to spoT7 and that a part of the RNA1 gene was also cloned into the same fragment. Gene spoT7 was localized on a 5 kb DNA fragment by further subcloning.

    Therapeutic effect of secretin in patients with jaundice; Double-blind placebo-controlled multicentric trial (1996)

    Notes: Abstract Secretin, a gastrointestinal hormone, has been shown to have a potent choleretic effect. Having already obtained some beneficial effects with secretin in patients with intrahepatic cholestasis, we sought to confirm its effects in a double-blind placebo-controlled study in patients with mild jaundice after acute or during chronic hepatitis, where total bilirubin level was in excess of 4.0 mg/dl for 3 days or more. Patients with primary biliary cirrhosis (PBC), primary sclerosing cholangitis (PSC), and familiar hyperbilirubinemia were excluded from the study. Ninety-three patients were included in this analysis, but the final evaluation covered 69 of them. No statisticaly significant differences were found in the reduction of serum bilirubin levels between secretin and placebo groups. As a number of patients with liver cirrhosis had been included, the subjects were subdivided into one group with cholestasis in hepatitis and one with liver cirrhosis. In the subgroup of cirrhotic patients who received secretin, serum levels of AST were significantly increased compared with the placebo group. However, since the choleretic effect of secretin is unique, further studies seem to be warranted.
